Description

The Experience

Join our dynamic team at Salesforce and make a real impact with your code! We’re looking for passionate individuals who want to shape the future of our products and deliver exceptional experiences to our customers. Equally important is advanced prompt engineering — the ability to write precise, structured prompts and cultivate the system context that makes AI outputs reliable, secure, and production-ready. Come be a part of our innovative and collaborative environment, where your skills will thrive and your ideas will be valued. Apply now and let’s build something extraordinary together!

We embrace the hybrid model and celebrate the individual strengths of each team member while encouraging everyone on the team to grow into the best version of themselves. We believe that autonomous teams with the freedom to make decisions will empower individuals, products, companies, and customers to thrive.

About the Team:

Authentication Core decides how every user, admin, and integration signs in to Salesforce. We own login flows, session management, MFA, and the OAuth 2.0 / OpenID Connect and SAML endpoints that issue and validate credentials at global scale. We also own the defenses around them: binding sessions to devices (DBSC and Web Crypto) to prevent session hijacking, rolling out mTLS, enforcing PKCE and refresh-token rotation for connected apps, and retiring legacy login protocols. A mistake here is a security incident or a global outage, so we hold a high bar for correctness, security, and operations.

Your Impact:

Your work protects every Salesforce customer’s front door. You’ll ship security improvements to hundreds of millions of users without breaking the integrations enterprises depend on.

What You'll Actually Be Doing

Architect, design, implement, test, and deliver highly scalable authentication and session services on Salesforce Core (Java), with strict availability and latency requirements

Build and evolve standards-based identity protocols, including OAuth 2.0/2.1, OpenID Connect, SAML 2.0, and newer ones such as PKCE, DPoP, mTLS-bound tokens (RFC 8705), token exchange, and Device Bound Session Credentials (DBSC)

Harden sessions and credentials against hijacking, replay, phishing, and credential stuffing, using token binding, refresh-token rotation, secure cookie design (SameSite, CHIPS), and step-up authentication

Threat-model new features, work with Product Security, and fix findings from penetration tests, bug bounty, and incident reviews

Roll out security enforcement safely for customers using feature flags, phased cohorts, telemetry-driven decisions, backward compatibility, and clear deprecation plans for legacy endpoints

Master our development process, culture, and code base, then improve it

Operate optimally in the hybrid engineering model where engineers are encouraged to be able to craft and complete the vital work to ensure quality in their own code as well as other engineers

Mentor others in development technologies, tools, processes, and secure-coding practices

Present your own designs to internal/external groups and review designs of others

Develop test strategies, design automation frameworks, and write unit/functional tests, including negative and abuse-case tests for authentication paths

Participate in the team’s on-call rotation to address sophisticated problems in real time, including authentication outages and security incidents, and keep services operational and highly available

Build and ship high-quality, production-grade software using modern engineering practices, with AI as a core part of your development workflow by pushing the boundaries of AI development tools to deliver secure, optimized, and high-quality code

Design and orchestrate complex systems where AI agents integrate seamlessly into human workflows, driving efficiency and innovation at scale

Contribute to building and maintaining the shared system context, an explicit repository of system designs, constraints, and standards that enables AI to operate accurately and reliably

Critically evaluate code (human or AI-generated) for correctness, quality, security, and performance, especially authentication, authorization, and cryptographic logic, where subtle mistakes become vulnerabilities

You're Our Person If...

A related technical degree required

3+ years of professional software development experience (Senior Level: 5+ years, including ownership of production services)

Strong Java and object-oriented design skills; experience with large, multi-tenant codebases is a plus

Solid grasp of authentication and authorization basics: identity vs. access, session lifecycle, and token types (access, refresh, ID), with hands-on experience with at least one of OAuth 2.0, OpenID Connect, or SAML

Working knowledge of applied cryptography: symmetric vs. asymmetric encryption, hashing, HMAC, password hashing (bcrypt, scrypt, Argon2, PBKDF2), digital signatures, PKI and X.509 certificates, TLS and mTLS, JWT/JWS/JWE, and key management and rotation, plus the judgment to use vetted libraries rather than writing your own

Secure-coding fundamentals: OWASP Top 10, CSRF, XSS, session fixation, open redirects, injection, timing side channels, and safe handling of secrets and PII

Understanding of the browser security model: cookies and their attributes, same-origin policy, CORS, CSP, and security headers

Proven understanding of web technologies, such as JavaScript, HTML5, JSON, and HTTP

Validated understanding of database technologies such as SQL and relational database schema design

Experience in automated testing including unit and functional testing using Java, JUnit, and Selenium

A demonstrated, genuine AI-first approach to engineering: using AI to move faster, build fluency across the stack, and contribute well beyond your core specialty, while using it responsibly with security-sensitive code (checking AI-generated cryptographic and authentication logic against specs, and never exposing secrets or customer data in prompts)

Experience using AI tools (e.g., Claude Code, GitHub Copilot, Codex, Cursor) in development workflows

Advanced prompt engineering skills and the ability to write precise, structured prompts and cultivate the system context that makes AI outputs reliable, secure, and production-ready

Excellent interpersonal skills

Office-Flex: Work in-person three days per week; or 10 days per quarter for some engineering teams

Even Better If...

Experience building highly scalable web applications or identity infrastructure (identity providers, SSO, federation, token services)

Experience with MFA and passwordless authentication (WebAuthn/FIDO2, passkeys, TOTP)

Familiarity with identity RFCs and specifications (RFC 6749, 6750, 7519, 7636, 8705, 9449; OpenID Connect Core), or participation in the IETF OAuth Working Group or the OpenID Foundation

Experience with HSMs, cloud KMS, or secrets-management systems

Experience in regulated environments (FedRAMP, GovCloud, FIPS 140-3 cryptography) <
